Frequently Asked Questions

Q Can I connect these batteries in series or parallel to increase voltage or capacity?

A: Yes! The modular design of the LFP12.8-150 enables increased flexibility for your energy storage system. You can safely deploy up to four batteries in series (e.g., to build a 24V, 36V, or 48V system) and up to ten batteries in parallel to massively expand your total Ah capacity.

Q Does this battery pack include a built-in Battery Management System (BMS)?

A: Absolutely. It is equipped with a robust built-in 4S150A BMS. This intelligent system continuously monitors and protects the cells against potential hazards such as overcharging, over-discharging, short circuits, and extreme temperature conditions, ensuring superior safety and prolonging the cycle life.

Q What are the recommended charging parameters for this LiFePO4 battery?

A: For optimal performance, the recommended charge voltage is 14.6±0.2V using a CC/CV (Constant Current/Constant Voltage) charge mode. The standard charger current is 30A, though the battery is engineered to safely handle a maximum charge current of up to 150A if fast charging is required.
